Scalloped yukon gold potatoes with some fontina cheese added to the mix. Really good.
Exactly how far over your head did this whole thread go…
Chicken and waffles.
Pretty sure many First Nations people would object to their traditional food being called “American” 
But if you’re going to be literal about it, you should probably at the very least include all of the Americas.
Admittedly, I do love churros…
Another who can’t stand the texture of tofu. I’ve had it prepared many times. Only found it palatable once and it was prepared by an immigrant.
Include some rolls. When my S went through his incredibly picky phase, when we were at church potlucks, it was often the only thing he would eat.
Thanks for these links. I didn’t realize there were so many things you could make with corn. I like that the 2nd link includes dishes from Central and South America, Mexico, and several places inbetween because those are the types of food my daughter likes, but there’s enough variety that I might be able to find something that will induce my son to try corn off-the-cob.
Cauliflower cheese is British but a good side. https://www.bbcgoodfood.com/recipes/358608/cauliflower-cheese
Hamburger stroganoff. 1 lb of ground beef, onions, 8 oz sour cream, 1 can cream of mushroom soup, and 1 can of beef consomme (or broth), water, and half a bag of egg noodles. The recipe was in a Betty Crocker cookbook in the 80s or before. My kids loved it.
My vote is for the meatloaf and mashed potatoes mentioned above by other posters. Very “plain jane”, fits the criteria of no sauce or gravy and would be easy to navigate for the recipient with the dexterity issues. Very easy to package and transport as well.
Isn’t meatloaf one of things that people only like if it’s made just like their mom made it?
My kids are very un-picky, but if someone serves them the tomatoey, soft, mealy kind of meatloaf, they won’t like it.
My formerly picky eater DD still will not eat meatloaf made by me or anyone else.
My mom put cheese slices on the meatloaf. It was one of the few things she cooked that I liked. Also, the mashed potatoes you can buy from a store (like Bob Evans brand) are pretty good (not saying good for you, but taste good). They travel & reheat well – better than homemade mashed potatoes would, at least better than mine. You can put them into a cassarole dish and stir them up before dropping them off if you don’t want them to know.
Well OP described the recipients as “friend-family” so presumably she will know whether or not they will eat her meatloaf.
Another thing I’ve noticed people tend to only like when it’s made the way their mom made it is potato salad. You’ve got the almost mashed mustard style, the chunky more mayo variety, the chunky mustard variety, with dill or without, etc.
This came through my emails today. Similar to chicken pot pie, very positive reviews and I’ve always had success with Ina Garten recipes.

My guys would like that @doschicos. I am going to give that a try.
I was thinking chicken and biscuits, too- so many quick versions. OP, will you mind making something elaborate, if they really just want a meal?
“chicken in the pot”. Bake bone-in, skin-on chicken pieces with carrots, potatoes, onions, flavor however you like. I do just salt and pepper personally. It’s plain and simple and delicious.
Or chicken and dumplings. I also put in onion, carrot and celery with the chicken/broth. I use Bisquick for the dumplings.
Pork tenderloin can be baked with a nearly endless numbers of seasonings. It’s also good with apples and onions in the crockpot.
Boston butt pulled pork in crockpot. With barbecue sauce though you said they don’t like tomato sauce, does that include barbecue sauces?
Fried chicken. (I don’t make fried chicken but many people do; I love it, I just can’t make it to suit myself)
Chicken tenders with sauces.
Meatloaf!
I’ll eat any version of meatloaf and just about any version of potato salad (both German and American style). My least favorite is when the potatoes are too soft, but I’ll still eat it. I put strips of bacon on my meatloaf.
I like your suggestions VaBluebird. Many picky eaters don’t like things that are mixed together. I was thinking beef stroganoff probably would be a no go for many. I used to make it without the sour cream and mushrooms when my kids were little, just beef with sauce and noodles. Pork tenderloin with sides such as baked potato or mac and cheese, glazed carrots. I like your chicken ideas above. Really good homemade fried chicken is a once or twice a year endeavor for me! When you make the baked chicken above do you use any liquid in the pot/ baking dish?
